MEANS FOR SEALING TH'E EDGES OF BEFRIGEEATOR-DOORS.

ingat Chicago, in the county of Cook and State of Illinois,'lhaveinvented a certain new and useful Improvementfin Means for Sealing theEdges of Refrigerator-Doors,A of which the following is a full, clear,concise,

and exact description, reference being had to the accompanying drawmgs,forming a.-

part. of this specification.

.My invention' relates to improvemnts in means doors.

T he object of my invention is to provide a simple and efficient meansfor sealing refrigcrator doors, and one of reliable operation. 9 '4 Inthe accompauying drawings forming a part of this specification Figure 1is a horizontal section of a pair of refrigerator doors and the adjacentdoor posts, (partly broken' away), showing the doors .and posts preparedto receivemy means of Sealing, the

doors bein'gin. closed position. Fig. 2 is asimilar 'view showing thedoors in partially open position. Fig. 3 is an enlargedl view showing infront elevation a portion of the surrounding door-frameV with my meansof sealing in position therein. Fig. 4 is a partial horizontal sectionof a door, door-post and my Sealing-device with'v the door in openposition. Fig. 5 isa partial horizontal section of a door, door-post andmy sealing device with the dcor in closed position.

.In the drawings 6,6 are hinged doors, 7, 7

' the wall of the door-frame surrounding Zthe door. The verticalupright-portions of this Vwallare more properly termed the posts, the

and I ythe horizontal upper portion the lintel. VAs

is equally applicable to the en-.. tiresurrounding wall of the door Iterm the.

horizontal lower portion the threshold,

my invention whole or any portion thereofhereini the surroundmg wall ofthe door-frame.

8 is a longitudinal channel to receive the backing strip for thepacking, 9 is the yieldink packing-secured to'the member 7'and extendingacross the -grooveor channel 8:

and issecured thereto'by wire brads i therein, 10 in connection With theflexibleV facing strip 11. l

VSprazification of vLetters Patent.

for sealing the edges of refrigerator i 12 is the backing strip,andfoonsists of a Patented Feb. 2, 19155..

- Application filed November 9,19'12. serial No. '2'a0,523.`

v.single trough like spring 'made of suitable material, preferablyspring steel, and conlongitudinal edges thereof 14; turned. in- Wardly.The said backing strip 13 is adapted to be secured Within the groove 8,and is provided with the perforations 15. to receive the screws 16,which se'cure the said spring within the groove 8 substantially alongthe longitudinal center thereof' The curvededges 14, 14 vof the spring12` provide two lines of contact between the edgel? of the door and thebacking stripor springl.

Vsisting of the curved member 13 vhaving the VVhen the door is in openposition, as illustrated in Fig. 4: of the drawings, the spring 12presses the yielding packing outwardly, and upon the closing of thedo'orthe packing is pressed first against the edge 17- ofy the door bythe edgelof the spring-12 nearest the door hinge 18, as thisside of th'espring yields with the closing of thedoor until the edge 17 of the doorcontacts with the' edge of the spring farthest removed from the spring18. The packing between the two edges of the spring remains somewhatslack', and the said. packing is pressed firmly against the meeting edgeof .the `door at the two edges of theispring, thus forming two lines ofypressure of the packing against theedge of the door and forming a n airspace within the trough of the spring andalso betweenthe two contactingedges thereof;

I ,claim In 'a'l refrigerator combination with a door and an adjacentmemberv having meeting edges when the doorl` parallel lines,, saidmeansincluding a spring member substantially semicircular in crosssection, the edges thereof being rounded and .engaging the inner sidesof said strip, said spring member being .flattened Vwlfen the door isclosed, said rounded /edgesI being thereby forced farther apart.
